Onychophorans, or velvet worms, are organisms with an extraordinary biology that remain poorly understood because of their cryptic lifestyle and rarity in the most ecosystems, particularly in the tropics (Podsiadlowski et al., 2008; Sampaio-Costa et al., 2009; Brito et al., 2010; Rota-Stabelli et al., 2010; Lacorte et al., 2011; Morera-Brenes, 2012; Chagas-Junior and Sampaio-Costa, 2014).

Onychophorans, or velvet worms, are small invertebrates that most biologists study in theory but due to their rarity, never see in the real life (Bouvier 1905, 1907, New 1995).
Using the new, as-yet-unnamed Chinese fossil as a guidepost, two researchers now suggest that some of the most enigmatic of these animals belong to the phylum Onychophora, which in the modern world includes the velvet worms of the tropics.
